PC Basics and TerminologySlide 2
Operating Systems What kind of "working framework" do autos use? Most keep running on fuel – in this manner numerous autos have a gas working framework, however a few autos have distinctive working frameworks. Diesel Hydrogen Electric SolarSlide 3
Operating Systems In a PC, the working framework is the PC code that controls the inner operations of the PC. This code is the thing that makes the PC go. Prominent Operating Systems Windows (95, 98, ME, 2000, XP, Vista) = Found on 90+ of the PCs [Vista is the most recent adaptation of Windows yet I would avoid it if at all conceivable. CALS has settled on a choice to not bolster it– Windows will soon declare Windows 7 which is an "altered" Vista] Mac OS – Found on Mac Computers. Panther is the name of the most current Mac OS. Linux – found on a couple of PCs (fundamentally the play area of PC nerds) Unix – utilized with centralized computer PCsSlide 4
Old Operating Systems CPM (Control Program for Microprocessors) Early PCs like the KayPro utilized this MS-DOS (Microsoft Disk Operating System) This was the ancestor to Windows All you saw on the screen was a C brief - >C You needed to sort a charge to get anything to happenSlide 5
Basic Computer Terminology CPU – Central Processing Unit The brains of the PC Major producers Intel (75-80 percent of the business sector) Pentium – Top of the line Celeron - Basic AMD (Advanced Micro Devices) 15-20% of the business sector Athalon – Top of the line Sempron – Basic Phenom – New Super CPU (quad center)Slide 6
What to Look for in a CPU Processing Speed The Old Days 4.7 Mhz mid 80s 10 Mhz mid 80s A turbo switch was required on PCs since some product couldn\'t keep running at 10 Mhz Today 3,000+ MHz is basic (3 Gigahertz) For most applications 3 GHz is sufficient speedier CPUs are required for video rendering and amusement playing yet there is an approach to enhance execution other than rate of the CPUSlide 7
Intel CPUsSlide 8
CPU Speeds The CPU makers are making light of velocity nowadays Instead they are advancing double center processors A double center CPU is essentially two CPUs in one body. So a double center CPU working at a slower speed can accomplish more one work than a standard CPU working at a quicker speed Intel and AMD have both as of late declared quad center CPUsSlide 9
What to Look for in a CPU GHz rating (speed at which the CPU operates). Get a CPU that is a couple ventures underneath the top rate CPU. You won\'t see a lot of an execution distinction, and you\'ll spare a considerable measure of cash following the speediest CPUs are essentially overrated. On the other hand on the other hand get a double or quad center CPU that works at a slower speedSlide 10
What to Look for in a CPU Bus (speed at which information is moved to and from the CPU) Currently 200 MHz is the most well-known transport speed (despite the fact that this is regularly reported as 400 MHz or 800 MHz as it is double or quad pumped). Numerous CPUs still keep running at 166 or slower however.Slide 11
What to Look for in a CPU Internal Cache (the snappy access memory that is on the CPU to hold late information). This memory is essential in speeding things up. At the point when contrasting CPUs, you might need to take a gander at the amount of reserve the CPU has. Be cautioned: Intel\'s Celeron CPUs have next to no store memory - that is the reason they\'re less expensive! Inside store is named L1 and L2Slide 12
What to Look for in a CPU Another thing to consider with CPUs is the micron size of the CPU unit. Littler sizes result in cooler operation and along these lines take into account higher check speeds. in principle this is something to search for, by and by it is troublesome.Slide 13
Basic Computer Terminology Memory RAM (Random Access Memory) More is better Determines what number of projects can be open at one time and what number of records can be taken care of 1028 Mb is the base I would consider (normally called 1 gigabyte - GB) 2-4 Gb of memory is favored Programs later on will require increasingly memory More memory is the way to augmenting PC executionSlide 14
Styles of Memory ModulesSlide 15
Types of Memory Modules SDRAM 1996 DDR RAM 2001 DDR2 RAM 2004Slide 16
Memory Modules Memory modules just connect to openings on the motherboard. They are anything but difficult to supplantSlide 17
Random Access Memory Think of RAM as a desktop, the greater the desktop, the more materials you can have out and open (I.e. the more projects you can have open and running). YOU CAN\'T HAVE TOO MUCH RAM.Slide 18
Basic Computer Terminology Motherboard The fundamental circuit board inside a PC, which contains the focal handling unit, the transport, memory attachments, development spaces, and different parts Various cards plug into openings on the motherboardSlide 19
Basic Computer Terminology Hard Drive An electro-mechanical gadget that stores information (programs, records) Typically alluded to as the "C" drive Generally, the greater the better MB (Megabytes) GB (Gigabytes) 80 GB is the base I would consider The Case, the internal partsSlide 20
Hard Drive Consider the hard drive to be the enormous drawer in a work area. It is utilized for capacity.Slide 21
Hard Drive Considerations Generally greater is better Size is measured in Gigabytes 80 Gig is the littlest I would consider Most of my PCs have 250+ Gig hard drives Digital photos, music and video "eat" hard drive space – 1 moment of video takes 1 gigSlide 22
Hard Drive Considerations Seek Time The time it takes the PC to locate a particular bit of information on the hard drive Measured in ms (milliseconds) The lower the number, the speedierSlide 23
Basic Computer Terminology 3 ½ Floppy plate drive Used for record stockpiling yet has restricted limit Often go in the A drive These are quickly getting to be out of dateSlide 24
Basic Computer Terminology 5 ¼ Floppy circle drive Rarely found on a PC today Often went in the B drive These circles were really floppy At one time in the beginning of individualized computing there were 8 inch floppies (IBM item)Slide 25
Basic Computer Terminology Zip drives A 100 M compress circle holds what might as well be called 66 little (3 ½) floppy circles 250 & 750 Mb were different sizes However it is much less expensive to simply compose documents to a CD or spare them to a USB drive These were prominent in the late 1990s and mid 2000s, preceding the times of USB drivesSlide 26
Basic Computer Terminology USB drives USB drives, likewise called thumb drives or blaze drive, are capacity gadgets that can be connected to the USB ports. They come in different sizes. A 4 GB thumb drive costs about $19.Slide 27
Basic Computer Terminology CD and DVD drives and burners Data can be put away on a CD Movies can be seen with a DVD drive Get one of every (that can compose)Slide 28
Basic Computer Terminology Video Card (likewise called Graphic Cards) An electronic gadget found on the motherboard that decides the attributes of how pictures will be shown on the screen. This card fundamentally telecasts video signs to your screen. Memory on video card is vitalSlide 29
Video Cards Video cards can cost several dollars People who play heaps of amusements are do realistic escalated work require top of the line video cards Dedicated "gamers" may introduce numerous design cards.Slide 30
Sound Card and Speakers Just relies on the amount you need to spend and how you jump at the chance to hear musicSlide 31
Network Interface Card (NIC) A system interface card (ethernet) permits your PC to be snared to a system of different PCs or the Internet Today most PCs come standard with a system interface card 10/100 is the standard (the 10/100 means the card is equipped for transmitting information at 10Mbps [Megabits per second] up to 100 MBPS). The innovation is quickly moving to remoteSlide 32
Modem A Modem permits the PC to attach to different PCs or the Internet utilizing a phone line. As rapid system access has expanded, there has been a decrease popular for modems. Be that as it may, it is keen to get a modem since they are CHEAP. Somewhat known actuality is that RoadRunner gives dial up access in significant urban areas. In the event that you have RoadRunner at home and travel, you can get to your email by RoadRunner Dial up – if you have a modem.Slide 33
Ports Plug in spaces on the PC so that peripherals, for example, printers, computerized cameras, scanners, can be associated with the PC. Serial Port used to be the standard Once about all printers connected to the serial port They contain either 9 or 25 pinsSlide 34
Ports Parallel ports are much speedier A serial port sends data through a link one piece at once, though a parallel port sends eight bits at once along parallelSlide 35
Ports USB (Universal Serial Bus) got to be well known quite a while back Computers ought to have no less than 4, ideal 6 or more USB ports. Can connect a group of gadgets to without the contentions exhibited by serial ports (in principle up to 127 gadgets can be associated) Faster than serial ports Most printers now connect to the USB port USB2 is the new standard Much quicker than standard USBSlide 36
Ports IEEE 1394 port or firewire port (Sony calls them ilink) Used for interfacing camcorders and exchanging video Very, Very quick If your PC doesn\'t have this port, overlook advanced film making A PC ought to have no less than twoSlide 37
Firewire (IEEE 1394) One must acknowledge there are 4 and 6 pin firewire ports (and interfacing links) Six pin are found on desktop PCs Four pin are found on tablets and computerized links.Slide 38
Ports Modern PCs have ports on both the front and back of the PC. (See the following two slides)Slide 41
